My hopes are that continued use of BP and participation with Lifestyles Unlimited will greatly accelerate my efforts.

You can use up to $25k a year of those passive activity losses if you are actively participating in your real estate ventures ("small landlord" exception) and income stays under $100k a year.So yes it can be useful if someone happens to fall under these circumstances, but for anyone who is going to have over $100k a year of retirement / other sourced income, they may be out of luck.It's all timing - you are just using up those PAL earlier than if you waited for the rentals to start producing taxable income (they normally do if it is a good investment), or a property is sold and PAL are released to offset that income. 

It is the opposite of active income, which is income received from a job or business venture that requires active participation.

Also the DSCR ratio at 7% cap rate is barely above 1.

Plus they are making it more expensive to participate.

If the ADU actually costs you $500K, it's barely worth it in terms of cashflow.

I was barely covering expenses and many months lost $100-$200.

They simply manage the bare minimum requirements of the transaction.

Since you are just graduating college you may already realize that it's not what you know, but who you know (as a personal note, I had college friends that were barely passing their classes however they ended up with really good paying jobs due to "who they knew").

Its a strategy that barely even worked few years ago but currently airbnb rents are DOWN across the board and LTR rents are UP, the trend changed last year due to so much airbnb supply it dropped the rates and airbnb also got stricter with cancellation fees as well as giving guest refunds more often.
